Consult a reference book listing the water chemistry requirements of the fishes and/or plants being maintained to determine the optimal range of GH and/or TDS. Remember to adjust pH and temperature of the water prior to adding it into an aquarium housing live organisms.
Determine GH and/or TDS in the aquarium prior to treating purified water with Remineralīz, then follow directions below accordingly. Shake bottle well before each use.
To increase GH/TDS in a pre-established aquarium: Dose up to 5 ml Remineralīz per 20 US-gallons per hour until desired GH/TDS value is attained. Changes to water chemistry, regardless of the parameter being adjusted, should always be done gradually rather than rapidly.
When preparing water for a water change: For every 10 US-gallons of water to be changed, add 5 ml (~1 capful) Remineralīz to purified water or tap water and mix thoroughly. Assuming a starting GH and TDS of 0, this will result in an increase of ~3.0 dGH and ~86 ppm, respectively. When employed at this dosing rate, 500 ml treats 1,000 US-gallons (3,785 L).
When preparing water for a new aquarium set up: Always adjust the water chemistry prior to adding live organisms to the aquarium. If setting up a planted aquarium and placing the plants into the substrate prior to completely filling the aquarium, adjust the GH, KH, pH, and temperature of the water in a separate vessel (e.g. in a large, clean pail or vat) before adding it to the aquarium. Do not add a large volume of purified water to the aquarium and then attempt to adjust the water chemistry afterwards, as this will be stressful to the inhabitants. Use the Advanced Instructions to calculate the amount of Remineralīz that will be required to bring about the desired change in GH/TDS to the volume of water to be used.
Advanced Instructions: Each ml of Remineralīz will increase the GH and TDS in 1 US-gallon of water by 6 dGH and 173 ppm, respectively. To obtain a specific GH and/or TDS value, divide the desired change in GH by 6 (or if TDS is preferred, divide the desired change in TDS by 173), then multiply this number by the net volume of water (in gallons) in the aquarium. Example: if the GH in 20 US-gallons is to be increased by 4 dGH, then add 16 ml Remineralīz (4 ÷ 6 = 0.8 ml per gallon; 0.8 ml per gallon x 20 gallons = 16 ml).
Caution: May cause eye or skin irritation. If in eyes, flush with water for 15 minutes, get medical attention. If on skin, wash thoroughly with water. Keep out of reach of children.
